Ruger Redhawk 8 Shot 357 Magnum: Personal Defense RevolverThe 8-shot .357 Magnum Ruger Redhawk does not require moon clips to fire, as it can headspace rounds on the cylinder rim, but they are recommended for faster reloading. Yes, the factory wood grips can be replaced with rubber alternatives, such as Hogue Monogrips, to reduce recoil impact on your hand.
Key Details regarding the 8-Shot Redhawk:
Moon Clips: The revolver includes three moon clips, which allow for faster reloads and faster ejection of empty casings, acting much like a speedloader.
Without Clips: Because .357 Magnum is a rimmed cartridge, the gun works without clips, although some shooters find that removing empty shells without the moon clip can be slower.
Grip Replacement: The standard wood grip panels can be removed by loosening the grip screw to allow installation of rubber grips like Hogue or Pachmayr.
